Yield:81864-47-3 69%
Reaction Conditions:
in methanol; for 5 h;
Steps:
6.5
Step 5: 7-mercapto-6H-2,3-dihydro[1,4]dioxino[2,3-f]benzo[d]imidazole [Show Image] The production obtained in the Step 4 (5 g, 30 mmol) was dissolved in anhydrous methanol (300 mL). Potassium ethylxanthate (7.1 g, 45 mmol) was added, stirred for 5 h. The solvent was removed, water and concentrated hydrochloric acid were added, and the reaction mixture was adjusted to pH 3, and extracted with ethyl acetate. The organic layers were combined and then washed with water and saline, dried, concentrated under vacuum to obtain a product (4.3 g, 69%).
